Plugins are a convenient way to group together related lua scripts.
Their primary use case is to group user scripts and their alert/status
definition.
The builtin ntopng user scripts and definitions are now
packed into plugins directories. In future, we will support loading of
user created plugins.
Plugins are loaded at startup into some runtime directories and then
used. Other changes provided by this commit include:
- Add sample flow logger plugin
- Initial support for system user scripts
- Rename edge to threshold
- Migrate system probes to user scripts/plugins
- Migrate scripts to more explicit alerts_api.checkThresholdAlert api
NOTE: The existing alerts configuration of the users will be discarded.
Some code has been added to make the current gui on/off toggle work.
It is marked with the following comment:
-- TODO remove after implementing the new gui
This provides a ~10x speedup by performing the JSON serialization work in C
(and thus avoiding Lua->C overhead). This also implements two in-memory alerts
queues (one for sqlite and one for the notifications) in order to reduce Redis load.
Alerts queue are now global instead of per-interface as there is only 1 dequeing thread.
- Alerts and flow status cleanup
- Community flow user scripts migration
- Implement scripts filters by l7 proto and packet interface only
- Migrate flow2statusinfojson
- Lower flow periodic update to 30 seconds if there is flow activity
- Display flow scripts without a gui section
Now periodic callbacks are properly called even when alerts are disabled
The granularity filter and check_function has been replaced with a more generic hooks list
